The change I made was exactly your first sentence: perform minimum sanity
checks, to ensure the basic operation of NPF. If the basic operation
cannot be assured, then fast-kick the packet.
If you pass the packet to the ruleset machinery, things can go wrong,
because the basic operation of the machinery cannot be assured.
And why not?
Because the stateful-inspection/ruleset-machinery/JIT-code/etc use the values
that were constructed when parsing the packet. If these values are wrong,
correctness of the operations is not ensured.
